A second nurse has been diagnosed with Ebola in Dallas, TX. With this the total number of Ebola cases in US has risen to three in one week.

Amber Joy Vinson, 29, is the second Texas Presbyterian Health worker to get the disease after caring for deceased Ebola victim Thomas Eric Duncan. She is being transferred to an Atlanta, GA, hospital with a bio containment unit.

Ms. Vinson flew to Dallas from Cleveland on a commercial Frontier Airlines flight, on October 13, before becoming ill. Dallas hospital workers who had contact with deceased Ebola victim Thomas Eric Duncan were ordered not to use public transportation. But Ms. Vinson violated the instruction given.

Nurse Amber Joy Vinson should not have taken the commercial flight to Cleveland on Oct. 13 because she was in an exposed group of Texas Presbyterian Hospital , and had a slightly elevated body temperature of 99.5 degrees, said CDC Director Thomas Freiden MD.

The US Centers for Disease Control and Prevention said there were 132 patients on the Frontier Airlines Flight from Cleveland that Ebola patient Amber Joy Vinson took to Dallas.

First nurse who contracted Ebola, Nina Pham, is recovering and so far no decision has been made about whether to transfer her to another facility, according to CDC officials.

There are only a few hospitals in US with bio containment centers. The federal bio containment centers are in hospitals in Omaha University Medical Center, Nebraska; Missoula, Montana; Atlanta, Georgia; and at a National Institutes of Health facility in Maryland.

The White House announced President Barack Obama has canceled fund-raising travel plans to New Jersey and Connecticut to hold a meeting this afternoon on containing the spread of Ebola.
